About GD&T Basics

For more than 10 years, individuals and companies have trusted GD&T Basics to simplify how they learn and apply Geometric Dimensioning and Tolerancing (GD&T). We focus on what matters most—clear communication of design intent. Our proven training methods cut through the complexity and give engineers, machinists, and inspectors the skills they’ll actually use on the job. Whether you’re an individual looking to boost your career or a team aiming to improve consistency and communication, we offer flexible training options: self-paced online courses, live virtual sessions, on-site customized training, and public workshops. Every program is built around practical application, not textbook theory. Our instructors are engineers, inspectors, and machinists who bring years of hands-on experience. They know the challenges of real drawings, and they know how to make GD&T click. The result is clear: professionals and companies communicate better, reduce costly errors, and simplify technical discussions. Companies see fewer disputes, deviations, and non-conformance reports—saving time, money, and scrap. GD&T Basics training prevents mistakes before they happen and improves collaboration across internal departments, suppliers, and customers.
